The Mortimer Building was a 19th-century building located at Wall Street and New Street in the Financial District of Manhattan, New York City. It was built by W.Y. Mortimer beginning on June 1, 1884, and completed for occupancy in March 1885. The architect was George B. Post. It fronted Wall Street for a distance of 57 feet (17 m) and New Street for 65 feet (20 m). Used entirely as an office building, the structure adjoined the New York Stock Exchange Building on the west and south. Tenants included lawyers, brokers, and bankers. The building was used as the general headquarters of the Industrial Workers of the World at its peak between 1912 and 1917. The New York Stock Exchange acquired the Mortimer Building for $745,000 in December 1918. Reasons for the acquisition included consolidating all the adjuncts of the exchange beneath one roof and the necessity for additional floor space for foreign issues, entertained by the NYSE. The site was valued at $710,000 in February 1920; $745,000 with the building included.

1. Interior design and history

Its rooms were light, arranged in suites and singly. The walls were made primarily of mahogany. The halls were wainscoted in marble and mahogany. The stairways were composed of iron and stone. The structure was considered fireproof from top to bottom. Modern conveniences included steam gas, electric lights, and two speedy elevators.

1. Previous structures

The 1884 Mortimer Building replaced an earlier edifice with the same name, built in 1835 by Richard Mortimer (1790 - 1882). The latter structure was constructed in accordance with the Mortimer estate, William Yates Mortimer executor. Richard Mortimer had commissioned another Mortimer Building at 935-939 Broadway from architect Griffith Thomas. This 1862 structure, which held the early offices of the American Institute of Architects, still stands as of 2018.

1 Wall Street

1 Wall Street (also known as the Irving Trust Company Building, the Bank of New York Building, and the BNY Mellon Building) is a 654-foot-tall (199 m) Art Deco skyscraper in the Financial District of Lower Manhattan, New York City, United States. The building, which occupies a full city block, consists of two sections. The original 50-story building was designed by Ralph Thomas Walker of the firm Voorhees, Gmelin and Walker and constructed between 1929 and 1931 for Irving Trust, an early-20th-century American bank. A 28-story annex to the south (later expanded to 36 stories) was designed by the successor firm Voorhees, Walker, Smith, Smith & Haines and built between 1963 and 1965. The limestone facade consists of slight inwardly-curved bays with fluting to resemble curtains. On the lower stories are narrow windows and elaborate entrances. The massing of 1 Wall Street incorporates numerous small setbacks, and there are chamfers at the corners of the original building. The top of the original building consists of a freestanding tower with fluted windowless bays. The facade of the annex is crafted in a style reminiscent of the original structure. The original building has an ornate lobby, known as the Red Room, with colored mosaics. The 10th through 45th floors were originally rented to tenants, while the other floors contained offices, lounges, and other spaces for Irving Trust. At the time of its construction, 1 Wall Street occupied what was one of the most valuable plots in the city. The building replaced three previous structures, including the Manhattan Life Insurance Building, which was once the world's tallest building. After Irving Trust was acquired by the Bank of New York (BNY) in 1988, 1 Wall Street served as the global headquarters of BNY and its successor BNY Mellon through 2015. After the developer Harry Macklowe purchased the building, he renovated it from 2018 to 2023, converting the interior into 566 condominium apartments with some commercial space. Sales of the condo units have been sluggish for Macklowe. The building is one of New York City's Art Deco landmarks, although architectural critics initially ignored it in favor of such buildings as the Empire State Building and the Chrysler Building. The exterior of the building's original section was designated as a city landmark in 2001, and the Red Room was similarly designated in 2024. In addition, the structure is a contributing property to the Wall Street Historic District, a National Register of Historic Places district created in 2007.

14 Wall Street

14 Wall Street, originally the Bankers Trust Company Building, is a skyscraper at the intersection of Wall Street and Nassau Street in the Financial District of Manhattan in New York City. The building is 540 feet (160 m) tall, with 32 usable floors. The original 540-foot tower is at the southeastern corner of the site, and a shorter annex wraps around the original tower. The original tower was erected on the site of the Stevens Building at 12–14 Wall Street and the Gillender Building at 16 Wall Street. It was built in 1910–1912 and was designed by Trowbridge & Livingston in the neoclassical style as the headquarters for Bankers Trust. A 25-story addition with Art Deco detailing, designed by Shreve, Lamb & Harmon, was constructed in 1931–1933 to replace three other structures. After new buildings for Bankers Trust were erected in 1962 and 1974, the company moved employees away from 14 Wall Street, and eventually sold the building in 1987. 14 Wall Street's tower incorporates a seven-story pyramidal roof inspired by the Mausoleum at Halicarnassus. The interior of the building contained numerous amenities that were considered state-of-the-art at the time of its construction; the first three floors were used as Bankers Trust's headquarters, while the rest were rented to tenants. A notable building in Manhattan's skyline in the early 20th century, the building was featured prominently in Bankers Trust's early imagery. The building was designated a New York City landmark in 1997. It is also a contributing property to the Wall Street Historic District, a National Register of Historic Places district created in 2007.

New York Stock Exchange Building

The New York Stock Exchange Building (also NYSE Building) is the headquarters of the New York Stock Exchange (NYSE), located in the Financial District of Lower Manhattan in New York City. It is composed of two connected structures occupying much of the city block bounded by Wall Street, Broad Street, New Street, and Exchange Place. The central section of the block contains the original structure at 18 Broad Street, designed in the Classical Revival style by George B. Post. The northern section contains a 23-story office annex at 11 Wall Street, designed by Trowbridge & Livingston in a similar style. The marble facade of 18 Broad Street contains colonnades facing east toward Broad Street and west toward New Street, both atop two-story podiums. The Broad Street colonnade, an icon of the NYSE, contains a pediment designed by John Quincy Adams Ward and Paul Wayland Bartlett, depicting commerce and industry. The facade of 11 Wall Street is simpler in design but contains architectural details similar to those at 18 Broad Street. Behind the colonnades at 18 Broad Street is the main trading floor, a 72-foot-tall (22 m) rectangular space. An additional trading floor, nicknamed the Garage, is at 11 Wall Street. There are offices and meeting rooms in the upper stories of 18 Broad Street and 11 Wall Street. The NYSE had occupied the site on Broad Street since 1865 but had to expand its previous building several times. The structure at 18 Broad Street was erected between 1901 and 1903. Within two decades, the NYSE's new building had become overcrowded, and the annex at 11 Wall Street was added between 1920 and 1922. Three additional trading floors were added in the late 20th century to accommodate increasing demand, and there were several proposals to move the NYSE elsewhere during that time. With the growing popularity of electronic trading in the 2000s, the three newer trading floors were closed in 2007. The building was designated a National Historic Landmark in 1978 and designated a city landmark by the New York City Landmarks Preservation Commission in 1985. The building is also a contributing property to the Wall Street Historic District, a National Register of Historic Places district created in 2007.
